SUPPORT FOR SPINNING-RINGS.

Specification of Letters Patent.

To LtZZ whom, it may concern.-

Be it known that I, MICHAEL H. MALONEY, a citizen of the United States, residing at Chelsea, in the county of Suffolk and State of Mas- .sachusetts, have invented anew and useful Improvement in Supports for Spinning-Rings, of which the following is a specification.

My invention relates to that class of spinning-ringsin which the ring is free to move, IO being supported when at rest upon a plurality of supports or points from which the ring when in motion is lifted and limited laterally and in its rising by lips which engage some portion of it. Rings of this class are made of 5 steel and have heretofore been supported upon a metallic hub or support which surrounds the opening in the iron rail through which the spindle projects. It has been found that when so supported the ring, although subjected to a drag from the yarn, does not always move freely and steadily, owing, it is believed, to magnetism, which serves as a counter-d rag to the rotating ring. The result of this irregu- V lar action in the movement'of the ring is to 5 cause corresponding irregularities in the product, resulting in a more or less breakage in the thread.

My invention consists in providing the ring with a hub, base, or support made of an insu- 3 lating material, preferably non-metallic and non-magnetic, by means of which the electrical conditions excited by the rotation of the ring are confined to the ring itself, and hence there is no counter-force excited in the hub or support by the rotation of the ring by which the ring will be retarded or made irregular in its movement.

I have also found that by supporting the ring upon, say, three sides in non-metallic and 4 non-conducting bearings of such character as to allow the ring a rotary and a free but small vertical play, so that its rotation will not be retarded appreciably by frictional contact therewith, the best results will be secured. Such bearings are preferably made of rawhide, which is well suited to the purpose.

My invention will be understood by reference to the drawings, in which Figure 1 is a sectional view-showing a por- 5 tion of a rail, the hub or support set therein, the ring, and the bearings therefor. Fig. 2

is a plan, and Fig. 3 is a detail showing the construction of bearings. Figs. 4: and 5 are modifications.

A is the ring, provided with a lower flange a and an upper flange (4, upon which runs the traveler a B B are the bearing-supports, each composed, preferably, of a hollow brass casing b, plugged with a piece of rawhide I), notched to provide an under bearing Z2 and an upper bearing 6 for the flange a of the ring, these hearings being slightly farther apart than the thickness of the flange a, so as to allow the ring a slight vertical movement, and the bottom of the notch in each bearing being preferably so placed with relation to the flange of the ring that the ring will rotate easily between them and Without any undue lateral movement.

Cis the base or support, which fits into the opening (Z in the rail D. This base is preferably molded of an insulating material, such as hard rubber or, better, a mixture of shellac and mica with or without other ingredients. Such a mixture is well known to electricians as an insulator and is especially useful for this purpose, because it can be molded to the desired shape, so that the expense of finishing is reduced to a minimum. Upon this base the bearingsBare mounted, preferably, in grooves, being screwed in place by screws or fastened in any other desired way. I prefer to mold into the lower part or sleeve 0 of the base or support a metal ring 0'.

In practice the base or support C is set into the usual spindle-opening in the ring-rail and is held therein by screws passing from one or both edges of the rail into the opening therein and butting against the metallic ring 0, which serves to take the pressure of the screws and prevent the base from cracking under the pressure. The use of bearings made from rawhide or the like will render the use of any lubricant unnecessary and will also prevent the formation of a bur on either the ring or the bearings. The spindle (not shown) rotates within the ring, and the rovingis brought down in the usual way through the traveler to the spindle.v

The drag on the traveler caused by the winding of the yarn or thread on the spindle causes the rotation of the ring at very high speed.

Such a speed would tend to excite electricity or magnetism were the base or support of iron or steel or were it omitted and the bearings mounted in the casings B directly on the rail. The use of an insulating base or support prevents any retardation or irregularity of movement due to such cause. The use of non-metallic bearings prevents any wear on the ring, serves in place of a lubricant, and also when used with a metallic base serves as a non-conductor of electricity. I have shown the best form of bearings now known to me; but such bearings as are shown in United States Patent No. 795,813 may be used instead.

1 have shown in Fig. & another way by which the metal ring 0' may be attached to the base. In this case a groove 0 is made in the metal ring and the base is cast so that a portion of its material protrudes into the groove. Of course the same result would be-attained if a projection 0 were made upon the ring, so that in the finished device the base would lie on both sides of this projection, as shown in Fig. 5, the point being to provide means for keeping the base and ring together.

What I claim as my invention is- 1. In a spinning-frame, a rail, a rotary ring, bearings therefor, and means for supporting said bearings upon the rail comprising an insulating-base to which said bearings are attached and which lies between said ring and said rail.

2. A rotary spinning-ring, non-conducting bearings therefor, and a base for supporting said bearings made from a non-metallic material, whereby electrical or magnetic currents induced by the rotation of the ring will be isolated in the ring itself.

3. A rotary spinning-ring, non-conducting bearings therefor, and a base supporting said bearings, constructed of material having small capacities for inducing electricity as described.

4. A rotary spinning-ring, bearings therefor composed of rawhide or the like, suitably supported, whereby electricity generated by frictional contact with said bearings will be isolated in the ring.

5. A rotary spinning-ring, and bearings therefor, each comprising a notched piece of rawhide or the like, and a casing adapted to hold each bearing, and means for supporting said casings upon the rail and insulating them therefrom.

6. In a spinning-frame, abase adapted to support ring-bearings, said base being provided with a sleeve having a metallic ring molded into its exterior as described.

7. In a spinning-frame, a base adapted to support ring-bearings and composed of insulating material molded into shape as described.
